gan-BOTTOM.

' Speciiication forming part of Letters Patent No. 49,434, dated August15, 1865.

' together with a like section of the bedsteadframe. Fig. 2 isatransverse vertical section thereof. Fig. 3 is a detailed view ot' oneof the corners ot' the bed-bottom to show the joint. Figli is arepresentation ofthe socket by which thejoint is secured.

ySimilarletters of reference indicate like parts.

This invention consists in an improvement in the supports ofthe slats ofspring bed-bottoms, and in their connections with such slats, and alsoin the mode of ]'ointing or securing the ends ot' their rails to eachother.

A represen ts a bedstead-frame, composed of parts a., side boards, b,and end boards, h, made in the usual manner. It is here shown supportingmy bed-bottom, whose frame, made up of two side rails, B, and two endrails, D, rests upon cleats fixed within the bedstead-frame. The ends ofthe end rails, D, are square, and are placed against the innersides,next the ends of the side rails, B, in such way as that the endsof the rail B shall be flush with the the outer faces of the end rails,D. In this position they are secured to each other by means of adouble-socket joint-piece, F, of peculiar shape, which is shownseparately in Fig. 4 in top view. This joint-piece is most cou'-veniently and cheaply made by casting. The

end of the rail B is received in a socket formed` by the angular sides ce, that portion of the rail which rests therein being formed to adovetail. The opposite side ofthe joint-piece F has also a socket, openonly. on its upper side, its side g' being plain, the opposite side, g,having a lip, which takes into a vertical groove, f,cut on the outerface of the rail D, and the bottom edges of the sides g g/beng unitedbyabottom piece, i, which supports the end of the rail D,

`as shown in Fig. 3. A joint-piece of like con-A .struction is placed oneach joint of the bedbottom.

The springs which support the slatsC are y designated by the letter E.They are each formed of one piece of wire, so that their two sides areconnected to make adoublesided spring whose ends are properly seeuredinthe rails D. Their sides rise on an inclination, which takes a directioninward from the rails D, and the said sides are connected at theirhighest point by the crosspiece d,which in this example is an integralpart of the wire,but i which maybe a separate piece rigidly fixed to thetwo sides ot' the spring. The length of this cross-piece is equal to thewidth of the slats, so that the latter", when resting thereon,may,asdthe springs are depressed,lie between their si es.

The slats C are of a length equal to that of the bed-bottom, and each ofthem hasapin,c, inserted through it near each end, which, pins areslotted transversely on their inner sides, as seen in Fig. 1, to receivethe cross-pieces d of the spring when the slats are placed thereon. Theslats are thereby locked to the springs, the tension of the springscausing the crosspieces d to draw constantly against the pins, and thuskeeping them in the slots of the pins when the slats 'and springs are intheir normal position. Moreover, the ends of the springs are bentslightly downward, so that their sides, when the cross-pieces are inplace on the pins, rise abruptly along the sides of the slats and serveto keep them from lateral displacement. When the springs are depressedthe slats are carried down still 'farther between the sides of thesprings.

The slats maybe of any suitable number and material, and if any of themshould become sprung or bent from longcontinued use, they can be turnedover and the pins d be driven through, so as to bring their slots on theop-y posite sides of the slats, the slots being cutin the middle of thelength ot' the pin for this purpose. r

My bed-bottom has several advantages over other spring bed-bottoms, andis also constructed differently from those now in use in severalparticulars. For instance, my slats run theentire length of the bed, andare easily detached from the springs, while the slats are entirelyindependent of each other. y

In some spring bed-bottoms now in use the slats are severally fastenedto the springs by leather straps, andvin order to prevent lateraldisplacement, the slats are also connected to each otherby aleatherstrap. Where the springs are made with only one side or armtheir coilsare usually kept in position by runningawooden roller through them,Whereas my springs need no such device, the springs being double andeach coil assisting to keep the other true. When the slats terminate atthe end of the spring the bedding droops and takes an ungracefnlappearance. My slats extend to the ends ofthe bed-bottom, and of courseprevent this ungraceful appearance.

My slats are removed by depressing the springs at one end, separatelyfrom thc slat,
